The OP is not trying to stop rocking. He is trying to stop the slight rolling of the tires. Semantics.
There in lies the problem. He needs both items. The X-chocks will stop the vibration or static movement of the tires but they are not designed to stop tires from rolling.
The one step will not stop vibration,shaking or static motion but it will stop the tire from rolling.
The OP wants to believes one device can do both.

The old Roto-Choks may have been capable but they are now defunct.
